| Outline of Final Research Achievements |
In this study models of lateral load - story drift relationship of RC columns with side walls are proposed which can be used in practical design procedures toward effective use of side walls. Firstly a series of tests on RC columns with side walls have been conducted to investigate the effects of the reinforcement details and the width and length of the side walls on the flexural deformability. The behavior of RC columns with side walls are characterized by two view points, i.e. high strength by contribution of side walls and high deformability after compressive failure of side walls. From this view point, finally in this study, simplified lateral force - story drift angle models for columns with sidewalls are proposed separating sidewall effects from overall behavior. In other word models for side walls and isolated columns are formulated separately. It is noted that the behavior of the overall member can be expressed as the envelope curve of two models.
